What happened today seemed impossible to many Americans six months ago.
But Fauci was right. And the US reached that bleak milestone much earlier than some experts predicted.
Since the first known US Covid-19 death on February 6, an average of more than 858 people have died from the disease every day.
Covid-19 is now the second-leading cause of death in the US, just after heart disease, according to the University of Washington's Institute for Health Metrics and Evaluation (IHME).
What happens next with the pandemic largely depends on personal responsibilityand how much Americans are willing to fight this battle together.
Already, Covid-19 has killed more people in the US than Americans killed in battle during the five most recent wars combined: the Korean War, the Vietnam War, the Iraq War, the War in Afghanistan and the Persian Gulf War.
And researchers project almost 180,000 additional Covid-19 deaths by January 1.
But it doesn't have to be that way.
"Increasing mask use to 95% can save nearly 115,000 lives, reducing that expected number of deaths by 62.7%," the IHME said.
And the same mask wearing, physical distancing and hand washing that protect against Covid-19 can also help avert a flu-and-coronavirus "twin-demic" that could overwhelm the health care system.
"We have to stay strong and do the things that could decrease the spread," said pediatrician Dr. Brett Giroir, the White House coronavirus task force's testing czar.
"Number 1: Wearing a mask when we can't physically distance. Number 2: Avoiding crowds. Number 3: Hygiene. And with smart testing, we can flatten the curve and slow the spread," Giroir said.
"We do have a formula to reduce the deaths, reduce the cases. But we all have to be disciplined and diligent to make sure we obey that every single day."
